As to the community for sharing journal articles, you should check out http://www.cross-x.com/vb/forumdisplay.php?f=59. This forum is largely servicing the high school debate community, though some college debaters post. Within this particular subsection called “Critique” forum much of the thinking and literature discussed here is also discussed there. There is even a sub-section called “Books and Articles” where you can make requests and help fill others requests. There is actually a good amount of articles and scanned books in the archives. Do realize that a substantial portion of the context in which these theorists and arguments are discussed is competitive debate. Enjoy! Take care
